// 1) Measure width of text at default font for all symbols in alphabet

// 3) Drop the top and bottom 10% (designed to ignore outliers like 'W' and 'I')
// 4) Calculate the average as the maximum scaling factor (designed to stop I becoming a rectangular blob).
// 5) Assume scale of zero would result in width of zero, interpolate scale required to make perfect width font
// 6) Draw text onto temp canvas at calculated scale
// 7) Find bounds of drawn text
// 8) Paint on to another canvas at the desired height (but only scaling width to fit if larger).
